I have material tested Butchers wax and also Staples wax.  Both
these waxes  are favoured coatings in the USA and do give a harder
finish than Renaissance Micro-crystalline Wax.  I have found however
that both Butchers and Staples attack lead and copper.  I assume
this is due to an acidic bees wax content.  For this reason I feel
they are not suitable for museum objects and I have decided to
remain with Renaissance Micro-Crystalline Wax which has fully past
material testing.

I would be interested to hear of other peoples experiences.
